Alex Rodriguez's ongoing arbitration hearing into his record-setting 211-game suspension for allegedly violating Major League Baseball's drug policy is supposed to be private.
But baseball fans have already gotten a taste of how far each side is willing to go to prove their case, including paying huge sums of money for evidence and -- one man who has worked for Rodriguez claims -- allegedly intimidating a witness.
The man asked for his identity to be concealed out of fear of retribution from Major League Baseball.
We asked him if he ever saw Rodriguez use a performance-enhancing drug.
"Never," he said.
He claims MLB investigators pressured him to say he saw Rodriguez and other players use PEDs and that if he didn't he might not work again.
"I didn't see it, no, but I was pressured. ... A certain pressure on the part of Major League Baseball," he said, according to a CNN translation.
The man told CNN he was not paid by baseball or Rodriguez, a three-time Most Valuable Player and one of baseball's all-time great sluggers.
The man's attorney says his client was questioned for eight hours at his house.
"It was definitely Major League Baseball investigators," Roberto Cuan said.
Major League Baseball Chief Operating Officer Rob Manfred strongly denied any improper conduct on behalf of his team.
"Our investigators have complied with all legal and ethical requirements throughout the process," he said.
He said that included the legal purchase of evidence. Manfred confirmed authorizing $125,000 for documents to find out about violations of the league's drug policy.
"There is nothing that is illegal or unethical about paying for documents. It's sometimes necessary to pay for documents for information."
But what if those documents are stolen?
The files in question come from the now-shuttered Biogenesis anti-aging clinic in South Florida, which MLB says supplied steroids to at least a dozen baseball players. A police report obtained by CNN shows the files were reported stolen from the car of a former Biogenesis worker.
The worker told police that MLB representatives had "offered him a job and up to $125,000 for the client files."
The last offer was March 18 and the documents were stolen six days later, according to the police report.
Manfred told CNN that no one from Major League Baseball knew the documents were reported stolen.
"In fact the people we bought them from made representations to the contrary," he said.
One of Rodriguez's attorneys, Joe Tacopina, doesn't buy it.
"Shocking. Shocking and deplorable," he said. "The things that they have done, the lines that they have crossed, the laws that they have ignored, the ethical violations that have been committed by members of the legal team. It's disheartening because Major League Baseball is supposed to be the pinnacle of a sports organization in this country."
Major League Baseball points out it isn't the only one paying for evidence.
It was revealed during the arbitration hearing on Rodriguez's suspension that his representatives admitted paying a lot of money for "evidentiary material."
"We've paid far less than they've paid in this case, first and foremost," Tacopina said.
